To all whom it may eoneem it known that i, iLRTHUP. J. Wmiss, :1 citizen of the United Eitates, residing at the town of West Orange, in the county of Essex, State of New Jersey, have invented a new and useful. Device for Regulating Supolemental Sn l Y of Fuel lliilizatuies and Air to Internal-Combustion Engines, of which the following is n speeiliea-tion, reIeL'enee being had to the accompanying. rlrmvings,

This device has for its object the ready supplying of fuel to internal combustion engines to facilitate the starting of the same, and is particnlaiily desirable in eonneci'on with automobile motors us the operation of the device may be controlled from the (lush. Fuel passing through this device may he pi'ogpm'tienecl no u'c l f" of the Suppl through the esi'liiu'e eui-burete' to {give its great eflieieney, must be adjusted oiregulun running. If the carburetor is :nliwtecl for starting alone, it will furnish rich :1 fuel. mixture -when the motor is wiirnml up. If the em-lun'etei' 1S ed ustecl high speed, it IS (lilihcult to start the i such adjustment. l l hei'e my regulator eviee is used, it is pi'eferi'ed to ilk l: 1st the carburetor for uvei'age running of the engine.

lily device ail hes for its object the 11 11- in-ission of ore air to the motor, thus thinning the fuel mixture, which very clesirfile when the engine is running high speed, thus cutting clown the quantity of fuel to maintain the running of the engine,

"- speed.

Referring; to thediziws Figure l a side View of my device whieh'is shown as attmrhed to the intake manifold of an automobile motor. if :2 another View of my device attached to the intake manifold of an autoi'nobile motor, looking the cleviee from the top, the intake manifold and the dash being shown in cross section. Fig. 3 shows the method of attaching the con nmni shown in c1ossseeti 1=n arranged so to SllOW the uhnission of the smallest quantity of fuel mixture through this device into the YliIn'lei oi the engine. Fig. l is another eh-wati on shown in cross section showing the device in such iosition us to admit a maximum amount of fuel mixture into the eylin (lGl'S o f the engine. Fig. 7 is a partial elevation of my device shown in cross section with the. plunger withdrawn so to shut oil? all fuel su ipl and admit only iiito the motoi'. l 8 a plan VlGW of my levies showing the plunger in sueh position as to bring the uel sumt-ly peits into register with the mneluit connecting with the intake umnilohl; and Fig; 5) is :1 Q7505 "'etion of my r gulator anti of :1 portion of she intake hi to which it nttaehetl'.

liel ewiiig in detail to the drawings, 1 is a plunger or piston mlnpteil to slide in the eylin i I piston fll'OVlt. cl with tuhulm' (ilhlllllfl-S e, on i'ii'uz; the openings 4 and 5 i'espei tive y new the opposite ends there of. When neutral position the openings land 5 a entirely closed so as to admit no fuel mi 'ture or uii into the intalminani folcl S, to which the said regulator is uttaelietl in. any convenient manner. In Fig. -12 of the drawings the device is shown in neutral position;

Referring to Fig. 5 the Piston or plunger 1 is shown in the position whereby thelennest' combination of fuel mixture may be supplieil through (lUVlUU. The air is supplied through the liuslm l into the n ehzuuheiand theliqnid fuel supis clmu'n through the huslung 3 which Fig. 6 the plunger 1 is shown in such position as to aclnnt the richest mixtuife of fuel to the cylinders, the an being sun this regulator device, A switched on to the battery or magneto 1n plied through the bushing 7 at atmospheric pressure While the raw fuel is drawn through the bushing 9 into the chamber 8 and mixed with the air admitted through the bushing 7, the mixture being drawn up through the ports 12, 13- and 14. In addition to'this, raw fuel is drawn through-the duct 15, the whole mass being drawn through the tubular chamber of the plunger into the intake manifold and from thence into the cylinders of the motor in the usual manner.

When the plunger 1 is drawn back to its full extent in the regulator cylinder the air ports 16 are opened, permitting air to be drawninto and through the pipe or conduit 17 connecting the regulator with the manifold.

The piston or plunger 1 is connected in a suitable manner such as by the rod 18 to the manually operated lever 19, a sleeve 20 being provided to protect said rod. A plate 24 is provided for use in conjunction with said lever, indicating the direction in which to move the same in order to provide a rich mixture or a lean mixture of fuel as may be desired, the lever being shown in a neutral position.

The device may be attached in any convenient manner to an internal combustion engine, the regulator control'lever being placed in a convenient position such as on the dash or steering post of an automobile.

In order to start a motor equipped with the spark plugs are the usual way and the lever is moved all the way over to the position indicated by :the "word rich in Fig. 2. This movement of the lever acting on the angle 21 which is pivoted at 92 and which in turn acts upon the rod 18., uhich connects with the piston 1, slides the said piston in the regulator cylinder 2 until the opening i is in register with the ports l2, l3 and 1% and the duct 15, and the opening 5 of the piston is in register with the pipe or conduit 17 connecting the regulator device with the n1anifold G of the engine. This position of the piston having been obtained through the movement of thelever to the position indicated by the word rich; the engine is turned over in any well-known manner as by a crank, the effect of which to draw the fluid fuel from the fuel chamber 11 through the pipe or conduit U, the screen 23 up through the bushing rate the mixing chamber 8 where it nos in contact with the air admitted at atmospheric pressure thrmigh the bushing 7', the source of air always being maintained at the same pressure and quantity, and the mixture is then drawn through ports 12, 13 and 14- and the liquid fuel. unadulterated with air being draivnthrough the duct 15, and the mass being then drawn by vacuum through the opening 41-, channel 3 and opening 5 into the manifold 17, and from thence into the cylinders in any well-known manner.

This operation brings the fuel mixture into contact with the energized spark plugs in the usual way and the engine begins to run. In practice it has been found that even when the atmospheric conditio is filr below zero, in practically every case ,"ille motor will start running upon a quarter turn where the ing order. v
